Prebiotics Explained: Why They're Half of the Gut Health Equation

In the world of gut health, probiotics often steal the spotlight. However, prebiotics play an equally crucial role, serving as the backbone for a thriving microbiome. This post covers the types of prebiotics, how they work with probiotics, and how Flore uses them in personalized formulas.

Understanding Prebiotics: The Unsung Heroes of Gut Health

Prebiotics are non-digestible fibers that nourish the beneficial bacteria in our gut. They are found naturally in foods like garlic, onions, and bananas, and are integral to maintaining a balanced microbiome. Unlike probiotics, which introduce live bacteria into the gut, prebiotics create an environment where beneficial bacteria can flourish.

At Flore Inc., we recognize that not all prebiotics are created equal. Our 40+ prebiotics are selected from the research. This commitment to precision allows us to craft personalized formulations that cater to individual gut health needs.

The Different Types of Prebiotics

Prebiotics come in various forms, each offering unique benefits to gut health. Here are some common types:

  • Fructooligosaccharides (FOS): Found in fruits and vegetables, FOS are known to enhance calcium absorption.
  • Galactooligosaccharides (GOS): Present in dairy products, GOS promote the growth of bifidobacteria.
  • Inulin: Commonly extracted from chicory root, inulin supports digestive health and boosts immunity.
  • Resistant Starch: Found in legumes and grains, this prebiotic helps regulate blood sugar levels.

Flore Inc.'s expertise lies in the ability to integrate these prebiotics into custom formulations, ensuring maximum benefit for each unique microbiome.

Synbiotics: The Perfect Pairing of Prebiotics and Probiotics

Synbiotics refer to the combination of prebiotics and probiotics, working synergistically to enhance gut health. By pairing these two elements, synbiotics optimize the environment for probiotics to thrive, ensuring the microbiome is well-balanced and functional.

Flore's individualized approach to synbiotics draws on more than 40,000 personalized formulations. Our formulas are informed by real-world human data, not only laboratory studies.

The Flore 40+ Prebiotics Library

Our Flore 40+ prebiotics library is a culmination of years of research and innovation. Drawing from up to 68 curated strains and 40+ prebiotics, each formulation is tailored to the person. Flore's published research includes a 2024 open-label pilot study in autism (mSystems, PMC11097633). In that study of 296 enrolled participants, formulas built from each person's own gut data were associated with increased gut microbiome diversity and reduced GI symptom severity over three months. It was not a randomized controlled trial, and Flore is working toward one in autism.

Flore acquired Sun Genomics in 2026, adding ten years of paired microbiome and outcome data. Sequencing is done by CLIA-certified partner labs.

Challenging Common Assumptions with Real-World Data

Many assumptions about gut health rely on generalized data from in vitro or animal studies. Flore Inc. challenges these assumptions by using real-world human outcomes. Our clinical provider portal and our partnership with Evexia Diagnostics give clinicians access to personalized probiotics.

For instance, the belief that all individuals benefit from the same prebiotic is dispelled by our data, which shows the importance of personalized approaches. Our formulations are custom-manufactured in an FDA-registered facility in Joliet, IL, to high quality standards.

Conclusion: The Flore Inc. Advantage in Gut Health

Prebiotics are indeed half of the gut health equation, and their role cannot be overstated. At Flore, we pair prebiotics and probiotics to your own gut data.
